I just replaced my kenwood 9902s with a pioneer 8400NEX. I already had the steering wheel interface module and it worked fine, the kenwood had a wire out of the harness labeled steering wheel control. I installed my pioneer and it doesn't have a wire for steering wheel control. Does anyone know which wire from the pioneer harness needs to hook up to the module wire for it to work? Any help is appreciated. I also can't get my samsung note 9 to connect wirelessly on android auto, i read other places that this is a issue with samsung. Any advice or updates on this? Thank You for any help advice you can give!

It's the headphones Jack style.

Thank you was just reading that too. Hopefully installer didn't cut the headphone plug off.
